The Cerebrospinal Fluid (CSF) Electrolytes Test measures the levels of key electrolytes—Sodium (Na⁺), Chloride (Cl⁻), Potassium (K⁺), and Bicarbonate (HCO₃⁻)—in cerebrospinal fluid (CSF). These electrolytes play a crucial role in maintaining brain function, neural activity, and overall homeostasis.
Why is the CSF Electrolytes Test Important?
🔹 Assesses brain and spinal cord function – Helps evaluate neurological disorders and metabolic imbalances.
🔹 Detects infections and inflammation – Abnormal electrolyte levels can indicate meningitis, encephalitis, or CNS infections.
🔹 Evaluates fluid balance – Helps diagnose conditions affecting CSF production, circulation, or absorption.
🔹 Monitors brain trauma or stroke – Electrolyte imbalances may result from brain injury or ischemia.
